Laser Spar Bags
The APS Rolled Sail Pro bag is an easy way to transport your mast (upper and lower still together) with the sail attached and rolled (battens removed). You can even leave your vang attached to the mast, and there is an area for your boom too. These bags are made with Topgun fabric so they hold up well to the elements. Standard spar bags come in basic zip nylon (one compartment) or 3-part sleeved versions to keep spars from dinging/scratching one another.
